Alaska SCLNG Project - Overview
Alaska SCLNG Plant Conceptual Layout
• BP, ConocoPhillips, ExxonMobil and TransCanada are working together to progress an Alaska LNG project: - 300+ people developed concept, $25M spent thru Jan13 - Key third party contractors engaged (URS, Fugro, exp) - Leveraging Denali, APP, related material ($700M past work)
• Concept work has defined key issues: - Integrated Basis of Design heat/material balance complete - Potential integration into existing operations - Required gas treating plant design (North Slope location) - Pipeline size and routing options (800+ miles, 42” x80 pipe) - LNG plant design (15-18 million tons per annum – “MTA”) - Gas off-take capacity for secure Alaska fuel supply - Preliminary capital estimate - $45-65 Billion (2011 dollars)
• Key project issues to address: - “Mega-project” challenges (labor, resources, equipment, etc) - Commercial and fiscal issues - Uncertainty related to permitting timing
• Forward Plans: - Use “Phased/Gated” process to advance project - Continue working together to optimize design

SCLNG Concept Summary - Upstream
PTU (62 miles east of PBU/GTP area) • Initial Production System (IPS) project in progress - 2016 SU • Preliminary SCLNG design basis for PTU: – Leverage IPS facilities, add fourteen new wells – Add new gas facilities to existing central pad / facilities – New 30” gas line from PTU to GTP in Prudhoe Bay – Peak workforce – 500-1,500 people
PBU Tie-in (adjacent to proposed GTP location) • Installation / tie-in managed by Prudhoe Bay Operator – Tie into existing CGF, deliver gas to new Gas Treatment Plant – Gas project / deliveries tied to future PBU operations
• Preliminary plan is to inject CO2 using existing injection systems

SCLNG - Concept Summary – Downstream
LNG Plant and Storage • Three 5.8 million tons per annum (MTA) LNG trains
- Plant receives 2.2 - 2.5 billion cubic feet per day to liquefy - LNG production varies with ambient temp (4.9 - 6.3 MTA) - Small volume of stabilized condensate produced (~1,000 bbl/day)
• Integrated utility system with all utilities on site • Two-three 160,000 cubic meter LNG storage tanks • Peak workforce – 3,500 – 5,000 people
Marine Offloading Facility • Conventional jetty and trestle design • Two berths • Design based on 15-20 LNG carriers • Marine support system includes required tugs, security boats • Peak workforce – 1,000 – 1,500 people
